I recently stuck lots of low growing sedum cuttings into an extra planting flat. I've also stuck them into small pots that weren't being used. Parts that broke off taller sedums and mums were stuck into pots with regular garden soil. If I weed and pull a bit off most any plant it gets stuck in somewhere else. With very little care from me many of these grow. It's nice to have extras the next year to stick in empty spots or give away. A friend at work thinks I'm very generous but it is probably really that I can't stand to compost a plant part that is easy to propagate :)

I've harvested seed from sunflowers, marigolds, cup plant, dill, cilantro/coriander, several pepper varieties, several tomato varieties, and have lots of other seeds from last year's harvest that will be fine yet next spring.

I also plan to edge a community garden area with ajuga that will be divided out of a badly overgrown clump. It should easily fill in 20 feet or more and let my clump perform better next year.

Just today took cuttings from a geranium I have had since my grandmother passed away 12 years ago. Brought in a bunch of herbs also.

Hosta, geranium, cup plant, big bluestem and many others. I planted most of the garden about 3 years ago, perennials mostly, and it is due.

When I went away to college, many years ago, I left my one houseplant with my brother, who inherited my room. Six months later I returned to find that he had not exposed the plant to sunlight or water in that entire period. I took a cutting, put it in water, and returned with it to college - and it came back! No idea what species, but refer to it as The Plant That Won't Die.

Not much, actually, because I'm trying to cut down on things in pots. I am rooting a few things I want multiples of, like jatropha, purple showers, butterfly weed, and things that have broken off. I'm gathering the bulblets of my dancing lady gingers, but don't know if I'll plant them or trade them.
